FOLDABLE BEDSPRING.

. Application filed November 22,1926. Serial no.,14e,s07.

This invention relates to a foldable bed spring. Q.

The principal objectofthe invention is .to provide a simple andinexpensive detach- I able connection for foldable sections of a bedspring frame permitting of the quick and easy attachment and detachment"of the frame sections when the bed spring is being set up for use orknocked down for folding the same, as for example when thesame is to bemoved. By virtue of my improved connection the matter of carrying thebed spring around corners in hallways and up and down stairs is relievedof all of its annoyances as the bed spring when folded up is ofsufficiently small and practicable size. Furthermore, the connection issuch as to be unnoticeablc when the bed spring is set up and mounted inthe bedstead, and is also ofsufficient sturdiness to give positiveassurance against breakage.

The invention is illustrated in the accompanving drawings wherein-Figure 1 is a perspective view of a bed spring of any standard orpreferred type having the end frame sections provided with my improveddetachable connection; and

Fig. 2 is a view looking at the inner side of one of the end frame spansshowing the angle iron frame sections joined in accordance with myinvention. the parts of the connection being shown partly in elevationand partly in section for purposes of better il-' lustration.

s a The frame of the bed spring 5 comprises the usual side members 6 andend members 7. I prefer to have the end. members 7 split at the middle.as indicated at 8, to provide separate angle iron frame sections 9 and10. arranged to be detachablv connected as indicated generally by 11.The connection, as will hereinafter appear, is such as to permit thesetting-up and knocking down of the bed spring frame with ease and fa- 5cility so that it becomes possible for a person to move the bed springsingle handed and without any appreciable difficulty in getting aroundcorners in hallways and up and down stairs. As will be noted in Fig. 1.

the detachable connection is hardly at all noticeable when the bedspring is set up,

due to the fact that it is contained within the angle of the angle ironframe sections.

Referring more particularly to Fig. 2, it

will be noted that the detachable connection 11 comprises a pair ofblocks 12 and 13 of rectangular crosssection t0 fit within the angle ofthe angle iron frame sections 9 and 10, as shown. The blocks are castwith relieved ends to provide attaching portions 15 ofangular crosssection permitting the riveting ofthe blocks securely to the framesections; as indicated at 16. Any formof attachment may be employedforassembling the blocks permanentlybn'the frame sections. The blocksare also cast to provide heads 17 and 18 arranged to be disposed inabutting relation at the adjoining ends of the frame sections. tangularsocket 19 cast therein, the walls of which taper inwardly, as shown. Thehead 18 has a rectangular boss 20 of complcmental form to the socket 19so as to fit wedgingly therein to provide for interengagement of theheads and properly align the frame sections. Openings 21 and 22extending lengthwise through the heads 17 and 18 are arranged toregister when the heads are interengaged so that a bolt 23 may be passedtherethrough to join the heads together. The head 24 of the bolt 23 isof reduced diameter so-as to be free to turn within the relieved portion14: of the block 13 and has a slot 25 to receive a screw driver wherebythe bolt may be turned in ti ghtening or loosening the same. A largesquare nut 26 is threadedly received on the end of the bolt 23 and isheld against turning when the bolt is tighten-ed or loosened by reasonof its engagement with the sides of there lieved portion 14-. of theblock 12.

It will appear from the foregoing that the attachment and detachment ofthe frame sections is a simple matteras the same involves a mere screwdriver operation. The

The head 17 has a reccross section arranged to the-\detaehahly,

as described above. The construction is ob viously simple andinexpensive as Well as unbreakable.

I claim:

In a foldable bed spring, the co1nbination with a pair of frame sectionsof :angle joined together, of a pair 01 blocks of rec tangular crosssection to fit within the-angles of the angle frame sections, saidbloeksbeing relieved to provide attaching portions of angular cross section tobe -secur ed with-in theQangle (it the angle frame seetions, the blocksprovi'ding alongside the relieved ,portions a pair of abutting lheadportions whereby the fbloeks rnay be ,detach ably joined toge her, .0116;o'f said 7 portions "having ,reetangnlar inwardly tapering socket, theothe "head ,ipn tion aving a .boss of complemental formifor Wedging:engagement ,in said. socket, openings provided in said head portions-,extending lengthwise with ,re-

tions together, said bolt having the headthereof-of reduced diameter tobe free to turn in the relieved portion of one of said blocks andprovided With a screw driver slot whereby the bolt may be turned intightening or loosening the same, and a ut in the relieved portion; ofthe other block and v.threa'dedly engaged on said :bolt and preventedfrom turning in the tightening or loosening of the bolt byreason of itsengagement ithrthe sides of'the relieved portion of the block.

In Witness of the foregoing I affix my signature.
